We interviewed Frontex’s deputy executive director in Evros and other Frontex officials in Frontex’s Piraeus office, but the “guest guards” of participating states deployed to Greece through Frontex indicated that they did not have permission to answer our questions regarding their experience in Greece. We corresponded in writing with Frontex officials during the research, writing, and editing phases of this report, which incorporates their comments on portions of an earlier draft of this report. 9 HUMAN RIGHTS WATCH | SEPTEMBER 2011
